To all whom t may concern.'

ABe it lmown that I, VERNON R. DON- CASTER, a citizen of the United States, residing at Orleans, in the county of Orleans, State of Vermont, have invented a new and useful Bottle-Cap; and I do hereby declare the following to be afull, clear, and'eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to a bottle cap', and has for its object to provide a device of this character which embodies novel clamping means for retaining the cap in operative position on the mouth of the bottle, said clamping means being controlled by a linger lever and being detachable from both the cap and the bottle.

Further objects of the invention are to provide 'a bottle cap by means of which the mouth of the bottle may be tightly sealed, which can be easily removed without any special form of opener, which can be used repeatedly, and which is of a substantial construction, so that it can be preserved and returned by merchants with the bottle.

With these and other objects in view, the invention consists in certain novel combinations and arrangements of the parts as will more fully appear as the description proceeds, the novel features thereof being pointed out inthe appended claim.

For a full understanding of the invention scription and accompanying drawings, in whichz- Figure l is a side elevation of the neck o ai bottle4 provided with a cap constructed in accordance with the invention, the clamping bail. and fin er lever being shown by full lines-in operative position, and by dotted lines in inoperative position.

Fig. -2 is a similar view, looking at the I bottle neck from a position at right-angles to that of Fig. 1.

Fig. 3 is a sectional view through the finger lever.

Fig. 4 is a side elevation of the bottle neck and cap, looking at the same from the side opposite to that shown by Fig. 2.

Fig. 5 is atop plan view of the bottle neck ,and cap.

Corresponding and like parts are referred to in the following description and indicated numeral l designates a bottle neck which is" of the conventional construction, the mouth thereof being adapted to be closed by a flanged cap 2. The interior of this cap may be provided withthe usual disk or lining arranged to engage,- and tightly seal the-mouth of the bottle when the cap is forcibly pressed in position thereon.

A downwardly facing hooked lug 3 projects laterally from one side of the bottle neck at a point slightly spaced from the top thereof, while alargerlug 4 projects laterally from the opposite side of the bottle neck, said lug being provided witha downwardly facing cam shoulder 4a. These two lugs 3`and 41 are preferably molded integral with the bottle, although it will be understood that they can be provided thereon in any suitable manner.

A clamping bail B extends transversely across the top of the cap 2, being preferably formed of a pair of crossed wires 5. At one end of the clamping bail the crossed wires 5 terminate in a downwardly extending loop 6 vwhich engages the hooked lug 3. At the opposite end vof theP clamping bail the extremities of the wires 5 are carried downwardly, as indicated at 7, and coiled around the ends of a transversely extending pivot pin 8, l The wire coils are shown at 7, while the pivot pin is shown as provided at its ends with the heads 8a, so that the pin is held securely against longitudinal displacement. This pivot pin 8 engages the inter-' Y mediate portion of a finger lever C, said finger lever including an upper arm 9 and a lower arm 10, which are disposed in a slight angular relation to each other. The

pivot pin 8 engages the finger lever at the intersection of the two arms 9 and 10, and

the arm 10 is provided at its lower end with an outwardly deflected finger piece 11.

As indicated by Fig. 3, the finger lever C is preferably formed by longitudinally doubling a thickness of material .upon itself,

the inner thickness 12 having the lower end thereof bent around the outerthickness 13, as indicated at 14, and being crimped at 15 to provide a bearing `for the pivot pin 8. This crimped portion 15 is at the. intervim) l"section of the vtwo arms 9'and l0 and bears against the side ofthe bottle to provide a fulcrum /for the lever when the nose 9a Aat the Aextremity ofthe arm l is in engage- .,ment with the cam face 4a of thelug 4.

When the finger lever C is inoperative position, as indicated by Fig. 1, the arm kthereof lits substantially against the side of the bottle neck, so as to be in alinement with the arms 7 of theclamping bail B,

- while the nose 9a of the arm 9 is inclined outwardly and in engagement with the clam face 4a of the lug il. In swinging the finger lever into operative position, the arm 9' thereof is swung outwardly, so that nose ,9a coperates with the cam face 4a of the lug vto draw'the clamping bail B downwardly a'hd force the bottle cap Vinto a tight engage Inent with the mouth of the bottle neck. It will also be noticed that when the finger lever is in, operative position, the arm 9 thereof is swung beyond a dead center relation to thearms -74 of the-clamping bail, so that thetension in the arms of the clamping bail serves to lockthe lever in position.

In4 order to remove the cap, the nger outwardly and upwardly, so as to release the bail, as indicated by dotted lines on Fig.

Al, and admit ,of both the bail and cap being bodily removed. The finger lever itself preferably has a resilient formation, so that any excessive strains will be taken' up without l; Gopiesiof this patent may be obtainedior five cents eachhby addressing Washington, D. C.

danger of breaking the lugs or pulling thel 4b clamping bail out of shape. The clamping bail itself can be easily formed from a single clamping bail extending across the top of the cap and having one end thereof looped for engagement with one of the lugs, a transverse pivot pincarried bythe opposite en'd of the bail, and a locking lever formed with a long .arm and a short arm having an an'- gular relation to each other, said linger lever In fact, merchants can being built up of two superposed thicknesses of sheet material and one offsaid thicknesses being crimped at the intersection of the arms to provide a bearing for the tubular pin anda fulcrurn for engagement with the bottleneck, the short arm of the lever being adapted to be forced outwardly under the before mentioned cam shoulder of one of the lugs for coperation therewith to draw the cap tightly against the mouth of the bottle when the long arm of the lever is being swung against thebottle neck. y A A In testimony whereofv I have signedmy name to this specification in the presence of two subscribing witnesses. v
